His stellar scientific contribution is most swiftly distilled by a random round-up of the things that bear his name: the Dyson sphere, Dyson series, Dyson graphs, Dyson number, Dyson operator, Dyson conjecture, Dyson tree, Schwinger-Dyson equation, Dyson’s transform, Dyson’s eternal intelligence – the last of which is something to do with dodging the heat death of the universe. As to his intelligence in the more demotic sense, he is quoted in one of my climatological bestsellers, “A Disgrace to the Profession”: The world’s scientists – in their own words – on Michael E Mann, his Hockey Stick, and Their Damage to Science Volume I:
“A model is such a fascinating toy that you fall in love with your creation… Every model has to be compared to the real world and, if you can’t do that, then don’t believe the model.”
Indeed. That’s as neat a summation as any of the petard on which the climate mullahs have hoist themselves, and also the big difference between a true scientist and activist hucksters like Mann. Dyson was not a “denier” nor any kind of “right-winger” (he loved Obama): As a scientist, he agreed that there was anthropogenic global warming partly caused by CO2 from fossil-fuel burning.Mark Steyn, “Cover Story” at Steyn On Line
Unfortunately, Dyson felt their sting because he saw a warmer planet as a good thing. “His own record prediction-wise was “a mixed bag”. But he always admitted he was wrong, and endeavored to explain why he was wrong.” More.

So it is unwise for scientists to make a big fight against the idea of intelligent design.” (2007)
